The idea of my SCP is a system of tunnels deep underground in Manu National park Peru, the tunnels never seem to end, the maze contains a creature that lives off of trap holes in the ground in which the local wildlife seem to fall in, as well as locals and tourists. The SCP foundation has found one of the holes and set up a small base of operations to try and find the creature. And most likely be sending down class-D to find the creature and get a good picture of what it is.

Hmmm… Well, there are quite a few 'never ending expanses of x's out there, but that doesn't necessarily means that its bad.
This is the kind of article that will live or die based off of the test logs included. You'd obviously have the standard 'D-class equipped with camera and recorder exploring" logs, but I would probably add a log of a very small tribe of survivors fighting off occasional attacks from the creature and living off of the trapped prey, alongside your idea of the foundation base of operations.

Oh, and there isn't much point collapsing your entire article. When it's that short, its just another click for everyone.

Thank you for the feedback, but I have a question. How would the foundation respond to a bunch of people trapped underground who have come in Witness with a horrifying SCP, would they have professional help like guards or MTF come and rescue them, or have the class-D lead them back to the lift.

Well… The foundation would probably have the D-class lead them to the way out, and the foundation would capture them. After a debriefing, they would most likely be terminated. You can't just give somebody amnestics and insert them back into society when they've been missing for months, that raises too many questions.
